When you see dyer's greenweed blossom, you know the summer has begun. However, you will not find this plant in many places in the Netherlands. Texel, Terschelling and Ameland are the best growing areas for dyer's greenweed. It grows in calcium-poor dune valleys. Although there are lots of possible soils for it to grow, it is a rare species that is declining strongly due to human influence: it is very sensitive to intensive grazing and fertilization. Dyer's greenweed was used as a dye in earlier times, which explain's its name.
